T III/Mill! it may calm/771,: Be it-known that I, HE-Nnr Knox BRYSON, l a'ci'tizen' of the lfnitedfStatcs, and a resident of Fayettcville, in the county of Lincoln and State of Tennessee, have invented a new and Improved Axle,ol' which the following is a full, clear, and exact description.

' The invention relates particularly to the construction of axle-spindles for vehicles; and the purpose of the invention is to provide a bearing forthe' hub of 'a wheel which will not only permit the wheel to turn'wit'h a minimum of friction, but which will also pro- '1 vidc a cushioned support for the hub, e'nabling the \'vheel to have a vertical .n'iovemcnt without lost motion, thus tending to l l i i render a'vehicle to whichsaid axle-spindle is l applied easy riding, i roads. v r A further purpose of the invention is to provide a construclirm of axle-spindle wherein should any accident happen to its eushiong envelop speedy rectification may be made by I any person of ordinary intelligence. g

The invention consists in the'novel construction and combination of the several parts, as will be hereinaft r fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improved spindle and a section through a hub adapted thereto. Fig. 2 is an outer face view of the outer cap-flange for the spindle. Fig. 3 is an end view of the spindle with the cushion-envelop removed. Fig. 4 is a vertical section taken practically on the line 4 4 of Fig. 1, and Fig. 5 is a section through a portion of the outer cap-flange of the spindle and the cushion-envelop therefor. V

A represents an axle, and a thespindle therefor, said spindle being an integral portion of said axle. The spindle a may be of any desired cross-sectional shape. For example, it may be circular in cross-section, or it may be rectangular or polygonal. Where the spindle connects with the axle, a flange 10 is integrally formed, the outer face of which flange is straight or smooth. The flange 10 is circular in general contour and is provided at its central portion with a vertical groove 1 1, extending from top to bottom, as is clearly shown in Figs. 1 and 3.

even upon very rough I through from top to bottom, said groove 11 of the cap-flange 12 correspondingto and being immediately opposite thegroove 11 of ,the integral flange 10 of the axle, as is also shown in Fig. 1. The cap-flange 12 is provided with a central rectangular or polygonal opening 1'3, which receives a. corresponding polygonal reduced member 13 at the outer end of the axle-spindle a. After the capllaugc 12 has been placed on the agile-spindle c itis held in position by meansofa nut 14 or the equivalent thereof screwed upon an o'utcr thrcaded'n'iember 1 5, integral with the spindle u.

l A cylindrical shell 16 is made to surround thespindle a, and said shell, which is open at its ends, extends'practically from the fixed flange 1()'to the removable cap-flange 12, as shown in Fig. 1, and thesaidshell 16 is pro-' vided at each end at top and bottom with pins 17, and said pins extend into the grooves 11 and 11 of the flanges 10 and 12, so that the shell, while it cannot turn around the spindle, is free to have vertical movement.

relatively to the spindle.

In connection with the shell 16 and the spindle a I employ one or more cushions B. When two cushions-are employed, as illustrated in the drawings, they are each of segmentalform and jointly fit around the spindle a and are in close engagement with the inner face of the shell 16; but it will be underadapted to the improved spindle, is greater in diameter than the customary bore for a hub, so that the hub 20 of the wheel 0 may be readily slipped over the shell 16 and will turn freely thereon. In order to reduce friction to the utmost. rollers 21 are introduced between the hub ..20 and the shell 16, and these rollers may be connected with the shell or may be connected with the hub, as may be found most desirable. I

When a spindle of the character described is employed, the wheel turns freely around the spindle, and at the same time the cushion and its accompan 'in shell permits the wheel to have vertical movement, so as to accommodate itself to irregularities in the road, audio that way the riding of the vehiele is rendered very easy and exceedingly pleasant. 1

Having thus described my invention, 1

claim as new and desire to secure by Letters i Patent 1. The combination with the wheel, of the axle provided with the spindle and with an integral flange between the axle and the spindle, said flange having; a vertical groove on its outer face, said spindle having a reduced polygonal portion at the end thereof, a capflan' e having a vertical groove on the inner face thereof, a nut threaded onto the end of the spindle for retaining the cap-flange in place, a cylindrical shell of greater diameter than the spindle encircling the same and on which the wheel is journaled, said shell having at the top and bottom of each end pins extendinginto the grooves whereby to guide the casing, and a hollow cushion encirclingthe spindle between the shell and said spindle, said cushion beingprovided with nipples 3 whereby to inflate the same, and the cap- E flange being provided with vertical slots for IGC1V1 I1g the nipples tom of each end pins extending into the grooves whereby to guide the casing, and a hollow cushion encircling the spindle between the shell and said spindle.

3. The combination with the wheel of the axle provided with the spindle and with an integral flange between the axle and the spin dle said flange having a vertical groove on its outer face, a cap-flange on the end ol the spindle and provided with a vertical groove on its inner face, a cylindrical shell of greater diameter" than the spmtlle encircling the same, and on which the wheel is onrnaled,

said shell having at the top and bottom of each end thereof pins extending into the grooves whereby to guide the casing, and a cushionencircling the spindle within the shell. I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
